Procurement Notes

Verify the specific ordering suffix EKFS against official Delta documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1008 package dimensions. Confirm RoHS3 compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a 10 µH inductance value is required for RF signal paths with limited current capacity. The unshielded nature necessitates careful PCB layout to minimize electromagnetic interference with adjacent traces. Verify that the 250 mA current rating aligns with the circuit's operational requirements to prevent saturation.
